Surface modification is the act of modifying the surface of a material by bringing physical, chemical or biological characteristics different from the ones originally found on the surface of a material. [1] This modification is usually made to solid materials, but it is possible to find examples of the modification to the surface of specific ...
Plasma activation (or plasma functionalization) is a method of surface modification employing plasma processing, which improves surface adhesion properties of many materials including metals, glass, ceramics, a broad range of polymers and textiles and even natural materials such as wood and seeds.
Surface engineering is the sub-discipline of materials science which deals with the surface of solid matter. It has applications to chemistry , mechanical engineering , and electrical engineering (particularly in relation to semiconductor manufacturing ).
Corona treatment (sometimes referred to as air plasma) is a surface modification technique that uses a low temperature corona discharge plasma to impart changes in the properties of a surface. The corona plasma is generated by the application of high voltage to an electrode that has a sharp tip. The plasma forms at the tip.
Almost always, silanization is the conversion of a silanol-terminated surface to a alkylsiloxy-terminated surface. This conversion confers hydrophobicity to a previously hydrophilic surface. [ 1 ] [ 2 ] This process is often used to modify the surface properties of glass, silicon, alumina, quartz, and metal oxide substrates, which all have an ...
Carbonitriding is a metallurgical surface modification technique that is used to increase the surface hardness of a metal, thereby reducing wear. During the process, atoms of carbon and nitrogen diffuse interstitially into the metal, creating barriers to slip, increasing the hardness and modulus near the surface.
The main reason why titanium is often used in the body is due to titanium's biocompatibility and, with surface modifications, bioactive surface. The surface characteristics that affect biocompatibility are surface texture, steric hindrance, binding sites, and hydrophobicity (wetting). These characteristics are optimized to create an ideal ...
Metals deposited by fluorosilane elimination include tungsten [32] and molybdenum. [33] As an example, the surface reactions for tungsten metal ALD using WF 6 and Si 2 H 6 as the reactants can be expressed as [32] [34] WSiF 2 H* + WF 6 → WWF 5 * + SiF 3 H WF 5 * + Si 2 H 6 → WSiF 2 H* + SiF 3 H + 2 H 2. The overall ALD reaction is [25]
